P0714 Acura Code - Transmission Fluid Temperature Sensor Intermittent Failure

Quick Answer

The Transmission Fluid Temperature Sensor is a thermistor-type sensor that changes resistance according to the change in transmission fluid temperature. Common causes include Faulty Transmission Fluid Temperature Sensor, Transmission Fluid Temperature Sensor harness is open or shorted, Transmission Fluid Temperature Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0714 Acura Description

The Transmission Fluid Temperature Sensor is a thermistor-type sensor that changes resistance according to the change in transmission fluid temperature. The Transmission Control Module (TCM) sends a 5 V reference signal to the sensor through a pull-up resistor. When the transmission fluid temperature is low, the sensor resistance increases and the TCM detects a high signal voltage. As the transmission fluid temperature rises, the sensor resistance decreases and the TCM detects a low signal voltage. When the engine is stopped and enough time has passed, the transmission fluid temperature will equalize to the engine coolant temperature. When the temperature in the transmission fluid temperature sensor deviates from the temperature in the Engine Coolant Temperature (ECT) sensor 2 after the engine is stopped and enough time has passed, the TCM detects a malfunction and stores a Diagnostic Trouble Code (DTC).

Frequently Asked Questions about P0714 Acura Code

1. What does the OBD-II code P0714 mean on an Acura?

P0714 indicates an intermittent failure in the transmission fluid temperature sensor circuit, which monitors the fluid temperature to optimize transmission performance.

2. What are the common symptoms of code P0714?

Symptoms may include erratic shifting, transmission overheating, poor fuel economy, illuminated check engine light, and limp mode activation.

3. What causes the P0714 code on an Acura?

Common causes include a faulty transmission fluid temperature sensor, damaged wiring or connectors, low or dirty transmission fluid, or issues with the powertrain control module (PCM).

4. Can I keep driving my Acura with a P0714 code?

Itâ€™s not recommended to drive for extended periods, as improper transmission fluid temperature readings can lead to shifting problems or transmission damage over time.

5. How do I diagnose the P0714 code?

Diagnose the code by checking the sensor wiring and connectors for damage, testing the sensor with a multimeter, and verifying the transmission fluid level and condition.

6. How is the P0714 code fixed on an Acura?

Repairs may involve replacing the transmission fluid temperature sensor, repairing damaged wiring or connectors, replacing the transmission fluid, or reprogramming the PCM if necessary.

7. How much does it cost to fix the P0714 code on an Acura?

Repair costs can range from $100 to $300 for sensor replacement or wiring repairs, but more extensive issues like PCM reprogramming may cost more.

8. Can low transmission fluid trigger the P0714 code?

Yes, low or degraded transmission fluid can cause incorrect temperature readings and trigger the P0714 code.

9. Is a transmission fluid temperature sensor failure common in Acura vehicles?

While not extremely common, this issue can occur, particularly in older vehicles or those with high mileage.

10. How can I prevent the P0714 code from occurring?

Regularly maintain your transmission by checking and replacing the fluid as needed, inspecting wiring and connectors, and addressing any transmission-related issues promptly.
